MLCC Manufacturing Equipment

What is MLCC?

MLCC is the abbreviation for multi-layered ceramic capacitors. These chip-type capacitors are designed to be small and large-capacity thanks to multi-layered (laminated) ceramic dielectrics and metal electrodes. The compact, heat-resistant design makes MLCCs ideal for high-frequency circuits, with frequent adoption in computers, communication equipment, video equipment, automobiles and most other digital equipment.
In recent years, electronics have become more prominent in automobiles, smartphones have continued to become more sophisticated, and IoT (Internet of Things) has become increasingly popular. This has brought a rapid increase in demand for MLCCs, which have proven to be highly versatile electronic products.

Koyo Thermo Systems MLCC Production Heat Treatment Equipment

As a manufacturer of MLCC production heat treatment equipment, Koyo Thermo Systems strives to solve various customer problems by using advanced technology and high-reliability manufacturing supported by an extensive delivery history. Although the company is able to provide a wide variety of equipment as a general manufacturer of heat treatment equipment, this page introduces only two representative Koyo Thermo Systems products.

Processing Applications

Koyo Thermo Systems MLCC production heat treatment equipment is generally used for ceramic dielectric binder removal and electrode firing, but equipment can also be designed to meet various customer-specific requests, including intermediate processing applications.

Features and Strengths

Manufactured according to the varied individual experiences of the manufacturer, MLCCs do not have a designated “standard” when it comes to manufacturing. In addition to its heat treatment equipment platform of simple, inert gas ovens and continuous mesh belt-type furnaces, Koyo Thermo Systems regularly provides one-of-a-kind customer-specific equipment. Koyo Thermo Systems supports high-quality MLCC manufacturing through advanced atmosphere control and heating control technology developed through years of experience.


Mesh Belt Type Continuous Furnace47-MT series

With a mesh belt construction and the adoption of a muffle, these furnaces offer excellent atmosphere stability and reproducibility. This makes them ideal for MLCC binder removal and electrode firing.

Since delivering the first furnace for the Japanese electronics industry in 1980, Koyo Thermo Systems has shipped over 4,000 mesh belt type continuous furnaces for manufacturing electronic components. The adoption of a metal muffle offers excellent temperature uniformity within the furnace. In addition, the created furnace atmosphere offers excellent air-tightness as well as improved stability and reproducibility. Adopting Moldatherm heaters featuring Koyo Thermo Systems’ heat insulation technology and advanced temperature variation characteristics ensures high-precision temperature control as well as excellent energy savings. This makes these products ideal for heat treatment lines in MLCC manufacturing.
An optional lineup of units for processing the organic exhaust gases generated during binder removal is also available, ensuring a wide selection of processing equipment suitable for any application.

Multi-inlet/exhaust type

With a muffle structure featuring multiple inlets and exhausts according to the work being processed, these models allow for fine-tuned atmospheric adjustment.
Products can be designed according to customer requests, such as with MLCC copper electrode baking requiring highly efficient binder removal, or processing requiring atmospheric changes at each step.

Organic exhaust gas treatment units

Inert Gas OvenINH Series

Max. operating temperature

This high-performance inert gas oven is capable of heat treatment at temperatures of up to 600°C in atmospheres with an oxygen concentration as low as 20 ppm. This makes the series ideal for MLCC binder removal.

Koyo Thermo Systems developed its inert gas ovens and clean ovens following development of basic technologies cultivated from atmospheric oven production. The company has now delivered over 4,000 ovens. Featuring a proprietary chamber structure and sealing technology, these inert gas ovens provide excellent air-tightness and temperature uniformity while also ensuring improved stability and reproducibility. In addition, the adoption of an external cooling mechanism powered by a cooling blower makes it possible to perform rapid cooling without affecting the furnace atmosphere, allowing for shortened processing times.
An optional lineup is also available—including organic exhaust gas treatment units and increased-safety specifications required for equipment dedicated to binder removal—to ensure safe and secure MLCC production.

Custom examples

A note on safety

In situations where binders and organic components are generated during product processing, ensure safety by performing treatment that considers the heating rate, amount of gas introduced, and other factors based on the differential thermogravimetric curve and other characteristics of the generated component.
